DETAILED DESCRIPTION OF THE INVENTION A. Overview

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 7 illustrate a reusable ground anchor 10, which comprises a shaft 20 having a pointed lower end 23, an embossed section 28 extending between lower and upper portions 21, 25 of the shaft 20 to retain the threaded upper portion 25 above ground 12, at least one helical blade 30, 40 attached to the lower portion 21, a stabilizer cap 50 mounted concentric on the upper portion 25, the cap 50 having an outer diameter greater than the helical blades 30, 40 and having a plurality of spikes 54, a first and second securing member 60, 70 threaded onto the upper portion 25 for holding the stabilizer cap 50 against the embossed section 28 and rotating the shaft 20 into and from the ground 12, the second securing member 70 having an outer diameter less than the first securing member 60 and an interchangeable mount 80 threaded to the upper portion 25. The interchangeable mount 80 having a housing 81 for covering the securing members 60, 70 and the upper portion 25 and optionally having an attachment 88 extending therefrom.

B. Shaft

The shaft 20 is generally comprised of a one-piece structure being of a metal, plastic or other rigid material to be the main structurally securing member of the anchor 10. The shaft 20 is generally cylindrical in an outer-diametric shape and may be hollow or solid.

The shaft 20 includes a lower portion 21 and an upper portion 25 linearly extending from the lower portion 21. The lower portion 21 is generally comprised of an elongated structure and is lengthier than the upper portion 25 to extend sufficiently within the ground 12 and retain the shaft 20 in the ground 12, wherein the lower portion 21 is inserted within the ground 12 and the upper portion 25 is retained above the ground 12.

The lower portion 21 is generally substantially uniform in diameter along a length of an elongated mid-section 22 of the lower portion 21 except for a pointed or tapered lower end 23 which is angled in such a manner for easy insertion within the ground 12 and extends from the mid-section 22 opposite the upper portion 25. The lower end 23 should be long enough to support the anchor 10 in a free-standing vertical position when the anchor 10 is pressed into the ground 12 by hand.

The upper portion 25 has threads 26 preferably extending along an entire elongated length of the upper portion 25 to threadably receive the securing members and the mount 80. It is appreciated that the securing members 60, 70 and the mount 80 may couple or connect to the upper portion 25 in other manners and thus other suitable connecting means may be utilized. The upper portion 25 is comprised of a one-size diametrically threaded structure to receive both the first securing member 60 and the second securing member 70, each of which have a same-sized threaded interior diameter defined by the openings 61, 71.

The shaft 20 also generally includes an embossed section 28 substantially separating the lower portion 21 from the upper portion 25. The embossed section 28 is generally integral with the shaft 20 and extends laterally therefrom for the stabilizer cap 50 to rest thereon and prevent the stabilizer cap 50 and upper portion 25 from being inserted within the ground 12 and also to prevent the stabilizer cap 50 from sliding onto the mid-section 22 of the lower portion 21.

C. Helical Blades

The helical blades 30, 40 are used to pull the shaft 20 within the ground 12 and to retain the shaft 20 within the ground 12. The blades 30, 40 are generally comprised of a rigid and strong material, such as steel including galvanized steel, mild steel, high carbon steel, and stainless steel. Other suitable materials having properties of strength, durability, abundance, and value may also be utilized.

Generally a pilot blade 30 and a main blade 40 are at least used; however more blades 30, 40 may be used as appreciated. The pilot blade 30 is located adjacent the lower end 23 of the lower portion 21 along the bottom of the mid-section 22 and the main blade 40 is located along the mid-section 22 between the pilot blade 30 and the embossed section 28. The outer diameter of the pilot blade 30 is also less than the outer diameter of the main blade 40 and any additional blades 30, 40 preferably follow a similar pattern where the higher the blade is located along the mid-section 22, the larger the outer diameter of the blade.

The pilot blade 30 is used to easily establish a pilot hole, allowing the main blade 40 to enter the ground 12 at the desired angle. Upon insertion within the ground 12, the pilot blade 30 and the main blade 40 become load bearing members for retaining the shaft 20 within the ground 12, the main blade 40 being the primary load bearing member to stabilize and prevent the anchor 10 from slippage and the pilot blade 30 being the secondary load bearing member for the anchor 10.

Each blade 30, 40 generally includes a body 31, 41 comprised of winding flat-structural member that forms a helix around the mid-section 22 of the shaft 20 with the ends of the body 31, 41 being vertically separated and generally forming a notch 32, 42 between thereof. The use of the notch 32, 42 reduces friction as the blades 30, 40 are rotated within the ground 12. An opening 33, 43 is formed concentrically with the body 31, 41 for receiving the mid-section 22 of the shaft 20. The body 31, 41 may be secured to the shaft 20 in various methods all which prevent the blade 30, 40 from moving relative the shaft 20.

The pilot blade 30 includes a continuous and integral sharpened edge having a first straight edge 35 a, a second circular or curved edge 35 b, and a third straight edge 35 c each following a respective peripheral part of the body 31. Likewise, the main blade 40 has a continuous and integral sharpened edge having a first straight edge 45 a, a second circular or curved edge 45 b, and a third straight edge 45 c each following a respective peripheral part of the body 41.

D. Stabilizer Cap

The stabilizer cap 50 is mounted upon the shaft 20, generally above the embossed section 28 and is secured thereto via the first securing member 60 for creating static pressure upon the ground 12 and to provide a stable and aesthetically pleasing base for the interchangeable mount 80 to rest upon either temporarily or permanently and also to prevent the anchor 10 from swaying after installation and keeping the original position of the anchor 10. The stabilizer cap 50 is comprised of a rigid and strong material, such as steel including galvanized steel, mild steel, high carbon steel, and stainless steel. Other suitable materials having properties of strength, durability, abundance, and value may also be utilized.

The stabilizer cap 50 generally includes a body 51 having a flat structure and generally square in shape and an opening 52 extending through the body 51 and preferably concentric with the body 51. The outer diameter of the body 51 is generally larger than the outer diameter of the main blade 40 or largest blade to prevent the stabilizer cap 50 from being pulled into the ground 12 and to sufficiently stabilize the anchor 10 to prevent the anchor 10 from tilting or moving relative the ground 12. The body 51 may also have gussets (not shown) in connection with the shaft 20 or other types of supports as necessary to retain the body 51 perpendicular to the shaft 20 or at another desired angle.

Extending downwardly from a peripheral edge of the body 51 at each of the four-corners is a stabilizing spike 54, wherein the spike 54 generally comprises a perpendicular bent portion of the body 51. The spikes 54 are for engaging the ground 12 and retaining the stabilizer cap 50 in place to prevent the stabilizer cap 50 from rotating. Generally, a spike 54 is located at approximately four-corners of the body 51. It is appreciated that the spikes 54 may not be integral with the body 51 and the spikes 54 may be separate components secured thereto. The bend of the spikes 54 relative the body 51 may also be various angles rather than 90 as appreciated. The spikes 54 may also be various shapes and in various numbers according to what is necessary to be inserted within the ground 12 and maintain the body 51 in a relative location and position.

E. Securing Members

Generally the anchor 10 includes a first securing member 60 positioned against an upper side of the stabilizer cap 50 and a second securing member 70 positioned against an upper side of the first securing member 60. The first securing member 60 and the second securing member 70 are comprised of a rigid and strong material, such as steel including galvanized steel, mild steel, high carbon steel, and stainless steel. Other suitable materials having properties of strength, durability, abundance, and value may also be utilized.

The securing members 60, 70 are preferably comprised of a threaded hexagonal nut structure with the first securing member 60 having a larger hexagonal outer diameter than the second securing member 70 to allow the first securing member 60 to accept larger wrenches or sockets than the second securing member 70 so the first securing member 60 may be accessed with the second securing member 70 also installed upon the threads 26 of the upper portion 25.

As implied, the opening defining the inside diameter of the first securing member 60 and the second securing member 70 is generally the same to be accepted on the threads 26 of the upper portion 25. Thus, the first securing member 60 and/or the second securing member 70 are irregular in an (exterior peripheral) outer diameter so that the first securing member 60 has a larger hexagonal (or other shape) outer diameter than the second securing member 70. The threads 26 along the interior of the first securing member 60 and the second securing member 70 may be any type of thread depending on application and according to the threads 26 of the upper portion 25.

The first securing member 60 is able to quickly accept a socket or wrench (over the second securing member 70) to tighten the first securing member 60 against the immobile stabilizer cap 50. The securing members 60, 70 may be threaded onto the upper portion 25 via a manual, electrical, pneumatic, or mechanical device to increase the static pressure in the ground 12 between the blades 30, 40 and the stabilizer cap 50, rendering the anchor 10 firmly embedded within the ground 12. Thus, the second securing member 70 does not need to be removed to access the first securing member 60 with a wrench or socket thus decreasing the time to install or remove the anchor 10 and also substantially preventing possible loss of the second securing member 70 when installing or removing the anchor 10. In an alternate embodiment, the second securing member 70 may also be comprised of a capped structure thus limiting the travel along the upper portion 25.

F. Interchangeable Mount

The interchangeable mount 80 is for creating an aesthetically pleasing structure on the portion of the anchor 10 above the ground 12 by covering the first securing member 60, the second securing member 70, the upper portion 25 of the shaft 20, and a portion of the stabilizer cap 50, and also for optionally retaining an attachment 88 therefrom. The interchangeable mount 80 is comprised of a rigid and strong material, such as steel including galvanized steel, mild steel, high carbon steel, and stainless steel. Other suitable materials having properties of strength, durability, abundance, and value may also be utilized. The mount 80 also effectively seals the first securing member 60, the second securing member 70, the upper portion 25 of the shaft 20, and a portion of the stabilizer cap 50 to prevent and slow weathering.

Generally, the interchangeable mount 80 includes a housing 81 having sidewalls 82, a top 83, and an open-ended bottom 84. Within the housing 81 is a securing member 86 comprised of a threaded fitting or threaded nut for receiving the upper portion 25 above the second securing member 70 and securing the mount 80 to the shaft 20. The securing member 86 may be affixed to the underside of the top 83 of the housing 81 or secured to various other locations; however the securing member 86 is generally connected to the housing 81 in non-rotatable manner.

The sidewalls 82 of the housing 81 generally extend the length of the upper portion 25 so that the bottom of the sidewalls 82 engages the upper side of the body 51 of the stabilizer cap 50 and the top 83 of the housing 81 extends over the upper portion 25 of the shaft 20. The outer perimeter of the sidewalls 82 and thus housing 81 may be substantially equal to or less than the diameter of the body 51 of the stabilizer cap 50 so that the entire lower perimeter of the sidewalls 82 is able to rest upon the body 51 of the stabilizer cap 50.

The attachments 88 may be attached at various locations along the outer surface of the housing 81 of the mount 80 or extend therefrom from various locations. The attachment 88 may be comprised of any fitting, sign, marker, etc. such as signs, posts, scaffolding, mooring ring, guy wire, etc. that can be permanently fixed to the top 83, sidewalls 82, other finished location, or other locations upon the mount 80. Thus, different mounts 80 may have different attachments 88 secured thereto, wherein to change an appearance the user simply has to interchange the mount 80 without having to remove the anchor 10 from the ground 12.

G. Operation of Preferred Embodiment

In use, assuming the desired location of insertion has been chosen, and the appropriate size and length of the anchor 10 has been chosen the anchor 10 may be installed. The opening 52 of the stabilizer cap 50 receives the upper portion 25 so the underside of the body 51 of the stabilizer cap 50 rests upon the upper side of the embossed section 28. The first securing member 60 is threaded part way (e.g. mid-way) upon the upper portion 25 of the shaft 20 and the second securing member 70 is threaded on the upper portion 25 against and above the first securing member 60.

The pointed lower end 23 of the shaft 20 is then inserted into the ground 12 until the ground 12 engages the pilot blade 30. The shaft 20 and blades 30, 40 are then rotated with applied downward pressure so that the lower portion 21 is fully inserted into the ground 12. The stabilizer cap 50 is also caused to slightly rise upon the upper portion 25 (since the securing members 60, 70 are not fully tightened) thus causing a portion of the upper portion 25 to be pulled within the ground 12.

A wrench, socket, or other tightening member is then positioned over the outer diameter of the first securing member 60 and the first securing member 60 is tightened to rotate downwardly upon the upper portion 25 and cause the stabilizer cap 50 to be sandwiched tightly between the embossed section 28 and the first securing member 60. By sandwiching the stabilizer cap 50, the upper portion 25 is raised above the ground 12 since the large circumference of the stabilizer cap 50 prevents the stabilizer cap 50 from being pulled within the ground 12 and the first securing member 60 pulls upward upon the upper portion 25 via being threadably tightened. Additionally, by tightening the first securing member 60 to cause the shaft 20 to rise, the ground 12 between the blades 30, 40 and the blade 40 and the stabilizer cap 50 is firmly compacted thus firmly embedding the shaft 20 and blades 30, 40 within the ground 12.

A smaller sized wrench, socket, or other tightening member is then used upon the outer diameter of the second securing member 70 to tighten the second securing member 70 by rotating the second securing member 70 downwardly upon the upper portion 25 until the second securing member 70 engages the first securing member 60 locking the first securing member 60 in place.

The desired mount 80 optionally having a desired attachment 88 thereon is then aligned with the upper portion 25 so that the securing member 86 of the mount 80 may be threaded onto the upper portion 25 and the housing 81 of the mount 80 conceals the first securing member 60, the second securing member 70 and the upper portion 25. The length of the upper portion 25 above the stabilizer cap 50 is preferably slightly less than the total length of the first securing member 60, the second securing member 70, and the securing member 86 of the mount 80 so that the securing member 86 of the mount 80 is spaced from the second securing member 70 and the mount 80 is able to rest upon the top of the stabilizer cap 50 for added stability. The mount 80 may also be welded or locked into position with a keylock bracket.

To remove the anchor 10 from the ground 12, the mount 80 is first removed. The second securing member 70 is then rotated partially upwards along the upper portion 25 to allow the first securing member 60 to be rotated partially upwards. A socket or wrench is then applied upon the outer diameter of the first securing member 60 in a reverse direction. The second securing member 70 prevents the first securing member 60 from rotating upwardly and as a reverse rotation is applied to the first securing member 60, the shaft 20 is forced to rotate with the first securing member 60 in a reverse direction thus causing the blades 30, 40 to reversely rotate and thus travel upwards and out of the ground 12. It is appreciated that if the depth of the tightening member is great enough, the second securing member 70 and the first securing member 60 do not need to be initially rotated upwardly to access the first securing member 60 for removing the anchor 10.
